To a/ZZ whom it may concern/:f o

Be it known that I, WILLIAM H. Sco'rr, acitizen of the United States,residing at St. Louis, Missouri, have invented a certain new and usefulImprovement inTrussed Bolsters, of which the following is a full, clear,and eX- act description, such as willY enable others skilled in the artto`which it appertains tov View of the modification hereinafterdescribed.

This invention relates to improvements lin trussed bolsters designed foruse more particularly as a truck-bolster, -though it is ob-A vious thatslight modifications Will adapt it for use as a body-bolster.

Referring to the drawings, A is a strut, B a compression member. Y

C is a tension memberhand D isa headblock. Y

The strut and compression member are of conventional form; but thehead-blockD and tension lmember C, which contain lthe elements of thepresent invention, are arranged as follows: The head-block D is providedwith the usual seat for the ends of the com-l pression member and hasprojecting therefrom the flanges 1, through which bolts 2 may beprojected through the flanges of the compression member to lock theseparts together. At the end of the compression member the head-block isprovided with the stops 3 and 3, which are formed, as shown in Figs.land 5, with a seat, in which laterally-projected andforwardly-extending members.- and i4 areY placed, said members extendingslightly over the end of the compression member, as best shownl in thefigures referred to.

block D is provided with the obliquely-eX- tended passage-way orperforation projected entirely through the same from inner to outer endlongitudinally of the tension member, which is threaded therethrough andbent downwardly parallel with the outer end por- The headf l tion of thehead-block, to which Said' tension member is riveted by means of therivets 5,

as best shown in Fig. l. It will be observed that .by reason of thepeculiar construction of the head-block a rigid supporting meansisprovided forthe ends of the compression v member, the filler 6, ofwedge shape, substantially filling the space between the com-- pressionmember and tension member, as best Shown in Fig. 1. y

In order to 'permit of securing the downturned end of thetension memberto the end vportion of the head-block, said head-block is Slightlyelongated beyond the usual'springseats and hollowed out to permit of theinsertion of necesssary tools to be usedin riveting. As the head-blockismeant to be formed of malleable castings, it is cored out, as shown inthe drawings, so as to provide the necessary thickness of metal topermit of proper malleation thereof.

In assembling the bolster the members et and ta are inserted in positionafter the compression member has been placed in its seat on thehead-block, the object of said members being to more firmly hold said`compression member in position. Y

I am awarethat minor changes in the construction, arrangement, andcombination of the severalpartsof my device can be made and substitutedfor those herein Shown and described without in the leastdepartin g frompression member; substantiallyas described. l 2. In a truss-bolster,head-blocks, a com'-r pression member secured thereto intermediatetheends of said member, ai seat'in said headblocks, and removable meansinsaid Seat, adapted to extend over the ends 'of saidcompression'member; substantially as dei scribed.

3. In a truss-bolster, head-blocks cast in one piece, having thereinseats for a com- I oo pression member, witha perforation extendingentirely through the same for a tension member, and a perforated endwall to which the tension member may be secured; substantially asdescribed.

4. In a truss-bolster,castmetal head-blocks having a seat, and anabutmentfor the end of a compression member, a tension member extendingentirely through said head-blocks, said tension member being bentdownwardly and connected with the end walls of said head-blocks;substantially as described.

5. In a truss-bolster, a channel compression member, a fiat-platetension member, and a head-block comprising a single casting providedwith a seat for said compression member, and with a perforationextending entirely through the same for said tension member;substantially as described.

6. In a truss-bolster, a head-block comprising a single casting providedwith a seat for a compression member and with a perforation extendingentirely therethrough for a tension member, said head-block having aperforated end Wall; substantially as described.

7. In a truss-bolster, a cast-metal headblock provided with a seat for acompression member, and a seat for a tension member, and havingvaperforated end wall extending downwardly from the tension ,member seatto which may be attached said tension member; substantially asdescribed.

8. In a truss-bolster, the combination with a channel compressionmember, a plate ten sion member, and a strut, of head-blocks comprisingeach a single casting for coperating with the ends of said compressionand tension members, each head-block being pro* vided with a perforationextending entirely through the same, through which perforation saidtension member passes, and means for retaining said tension member inplace; substantially as described.

In testimony whereof I hereunto aftix my signature, in the presence oftwo witnesses, this 14th day of May, 1903.
